Allergic asthma is a chronic inflammatory lung disease mediated by type 2 cytokines produced by T helper 2 (Th2) cells as well as the recently discovered group 2 innate lymphoid cells (ILC2). Due to a lack of unique markers, the accurate phenotypic characterization and quantification of ILC2 requires a comprehensive panel of fluorescently labeled antibodies. The markers that are currently used to characterize ILC2 have not been standardized and often vary between research groups, which poses significant challenges when comparing data. Intranasal administration of the pro-inflammatory cytokine IL-33 in mice is associated with strong, Th2 cell-independent ILC2 activation. ILC2 are also activated in mouse models of allergic asthma based on the physiologically relevant house dust mite (HDM) allergen, which parallel eosinophilic airway inflammation observed in asthma patients. Here, we describe the analysis of ILC2 by flow cytometry in these two commonly used allergic airway inflammation models in the mouse.
